They might start pts next week but they are not going to release a new biome without due diligence on a test server first. These devs are nothing if not thorough in their approach to game design and implementation. So just cool your jets. We will get it when we get it.

Sorry kids, we are in fact not there yet.

And when it arrives, within 2 hours or maybe days if we're lucky, there will be a new hue and cry (heavy on the cry) for the next biome cuz this one was too small, too hard, too easy, too boring, too this, too that... and the whole process of calling the game dead, the devs loafers and the game abandoned begins again.
Gamers are nothing if not consistent in their neediness.
